It's a dirty galaxy out there but someone has to image it.

It's funny...growing up our parent said, "clean up that dust!" Yet, when the Milky Way does it, we all say, "Ooh! Look at that dust!" It doesn't seem fair.

Anyway, this was my first attempt at something that is primarily a dark nebula. Processing was pretty straightforward:

I used the relatively new NormalizeScaleGradient script for this and it definitely made a small but noticeable improvement.

Lum:
Dynamic Crop
Deconvolution
ABE
TGV Denoise
Histogram Transformation

Each R G and B:
Dynamic Crop

TGV Denoise

RGB:
Channel Combination (R, G, B)

EZ Star Reduction script (Adam Block's method)
Curves contrast & very slight color boost
Dark Structure Enhance script
Adv Sharpening script

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
